BUSHING-REDUCER 6B4661 - Caterpillar

The Electronic Control Module (ECM) monitors engine operating conditions such as low oil pressure or high coolant temperature. If an operating condition exceeds the normal condition, an event code is generated. The event code will be active until the condition returns to normal. The ECM also logs the event. Events usually indicate a mechanical problem instead of an electronic system problem.Events can be in the form of a warning, a derate or a shutdown. The events that are available for this application can be found in this section of the document.

Output voltage from a typical analog temperature sensor
Illustration 1 shows the typical output voltage from an analog sensor. If the output signal voltage is between 4.2 VDC and 4.8 VDC, the ECM will generate an event code.Monitoring System
The electronic service tool can be used to program certain monitoring system parameters. Certain features can be enabled or disabled and some of the trip points can be set.Refer to the table for monitoring system parameters in Troubleshooting, "System Configuration Parameters" for the various features that can be programmed.The following actions will be taken when an event is occurring:"Warning" - The warning lamp will come on continuously while the event is occurring."Derate" - The warning lamp will flash while the event is occurring and engine power will be derated."Shut down" - The warning lamp will flash while the event is occurring and the engine will be shutdown.If multiple derates are active, the derate that limits the most power will be the derate that is shown.When a selected monitoring system parameter is programmed to "Off", the ECM will not take any action on the event. For example, the warning lamp will not come on.Cross-Reference for SPN-FMI Code to EID (Events)
